“…The long-term results of minimally invasive shelf acetabuloplasty are parallel to or better than those via the extended approach. The postoperative follow-up of minimally invasive approaches is simpler with a short hospitalisation time or ambulatory procedure, no rehabilitation, moderate pain and no scarring or aesthetic effects [16][17][18][19] . Not only does periacetabular osteotomy have a more complex postoperative follow-up and lengthy consolidation with no weight bearing, but most of all, there is approximately 12.5% serious complications and 31.6% mild complications 3 .…”

This is a retrospective, single-operator study which hypothesised that shelf acetabuloplasty for acetabular dysplasia with a centre-edge angle of Wiberg between 0° and 15° and stage 1 or 2 osteoarthritis, has comparable results to periacetabular osteotomy with less severe complications. Patients and methods: 95 hips, mean follow-up of 12.8 years (4-26.4), 70.5% female (67/95), 29.5% male (28/95), mean age of 34.7 years (16-61 years). The surgical technique was minimally invasive, intermuscular between the posterior border of the tensor facia lata muscle and the anterior border of the gluteus medius muscle as described by Chiron in 2007. Survival curves were analysed using the Kaplan Meier method with the Log Rank test; Cox power test: 0.832. Results: Complications: 4 graft lyses (4.2%); 3 non-unions (3.1%); 56.8% (54/95) screw removal; no infection, no lateral femoral cutaneous nerve injury, all low-grade complications with no high-grade. Total hip replacements: 22.1% (21/95) of which 52.3% (11/21) were in the first 5 years. Age and gender had a significant impact on survival: under 30 years, 13.9% (6/43); over 30 years, 30% (15/50); under 25 years, 0% (0/13; mean follow-up 14.6 years; 9 -26); females, 26.8% (18/67), males, 10.7% (3/28). Survival: Overall (5 years: 90%, 10 years: 83,5%, 15 years: 77%); according to age: under 30 years (5 years: 95,3%, 10 years: 88,8%, 15 years: 84,3%), over 30 years (5 years: 84%, 10 years: 77,4%, 15 years: 69%), P-value 0.0004; according to gender: females (5 years: 86,3%, 10 years: 77,4%, 15 years: 68,9%), males (5 years: 96%, 10 years: 92,1%, 15 years: 92,1%), p-value: 0,0826; females over 30 years (5 years: 80,4%, 10 years: 75,1%, 15 years: 64,4%), females under 30 years (5 years: 91,6%, 10 years: 87,3%, 15 years: 80%), P-value: 0,1502 Survival rates were similar to those for peri acetabular arthroplasty, with no serious complications. Checking for any associated labral hip tears and arthroscopic treatment beforehand should improve the total hip replacement rate in the first 5 years. Ideal patients are young males and those at risk are females over 30 years of age, but with results that are still acceptable for group at risk which justify this minimally invasive procedure
